The construction illustrated in tlic 'drm-i'- ings comprises a'hollow journal box 10 provided with threaded apertures '10 by means of which u connection is made between the journal box unil the car truck. The car axle ll extends into the journal box from the inner end thereof, und the inner end of the box is Closed by an end wall l2 which is secured thereto :ind which is provided with iin annular recess 13 adopted to contain parking; motori-,il ll which coacts with the periphery ot thc rar axle and prevents dirt sind other infiteiinls from entering the interior of the, box.

and these end? portions are turned-down to form projecting trunnions 33' of smaller dienieter which arc adapted to rotiite in the cylindrical 'recesses 34 sitelyv disposed fares o rings of tl'ie axle.

sind the rollers of @zich group ai@ mounted between two pairs o f retaining ringe 35.

-into fthe? Vare mounted between the reduced 20 of the rollers, as illustrated particularly rFliese retaining rings areof a diameter sliglitly larger than that of the steel busli ing 17, and they are held outwardly therefrom by the rollers 20,'Which are lar er in diameter than the radial width of t e retaining rings. l

The retaining rings of each set of rollers are connected to ether and held in the proper spaced relation gy the transverse connecting rods or pin's'38, which .are4 rovided wit are adapted to rotate on the pins between.

the rollers and the'retaining-rings and lthey rtions in Figs. 2 and 4. lhe spacing rollers 40 are smaller in diameter than the bearinerollers 20, and the pins 38 which serve as arl forV the spacing rollers are mounted wit their centers on the arc of a 'circle' which is smaller in diameter than the circlecontain ingr the center lines of the axesof the rollers 20, so that the spacing rolleis are located in'-,

bearing rollers d wardly with respect to' the 20 and are in direct lines between the centers of the roller bearings, as illustrated in Fig. 2, thus materially reducing the outward thrust on the spacing rollers and the pins.

It will be apparent that the foregoing construction providcs an anti-friction roller bearing device between the axle and the journal box; so that the friction between theseparts is reduced to a minimum and at the same time the necessary endwise movenient of the axle is permitted without cause lng unnecessary wear or friction by reason of the fact that some relative movement of the roller bearings is permitted longitudivnelly of the axle between the shoulder 11 of the axle and the collar 15. The end thrusts of the axle are received bv the ball-bearings 25 carried by the end wall 22.

Although l have described one embodiment of the invention for pur oses of illustration` it will be understood t lat it may be constructed in various other forms without departing from the scope of the appended n i l claims.

l claim:

l. In combination, a journal box having an end wall, an axle extending into said box and terminating opposite said end wall, a plaie secured to said end wall, a roller bear' ing carried by said plate'and adapted to coact with the end of said axle, said end wall and said plate having centrally located apertures therethrough and a removable block adflilpted to close the aperture in said end wa 2. In combination, ajournalbox, an axle extending into 'said journal box, retaining rings extending' around vsaid' axle, rollers having trunnions journalled in said retainmg rings, spacing rods uniting said ,retaining rings between said rollers, said-spacing rods. being out of contactwith said rollersV aiidfbeing located in planes containing the center lines of adjacent rollers, and spacing rollers rotatably mounted on said spacing rods at theends of` said first named rollers` 3. In combination, n journal box, an axle extending into said journal box, retaining 'rings extending aroundsaid axle, rollers having reduced rcylindrical end portions and trunnions extending from saidv end portions t0 engage said retaining rings, spacing rods Aconnecting said retainingr rings between said lfblle'rs, said s acing rods being out ofcoutact with said) rollers and being located in planes containing the center lines of adjacent rollers, and s acing roll econ the endls of said spaeiil'ig rods and -eo- 'a ing with the peripheral su aces of thereced end portions of said rst named rolle'rs,'saidspacing rollers bci-ng out of contact with the bearing' surface of said axle. Y'
